9 Claims.

This invention: relates to improvements in metal studs. andjoists for use:-

building constructions.

The. object of the invention to form studs and joists of angle ba-rs: forming longitudinal cornor members, and transverse braces formed of wire, thereby providing studs joists: which are light weight and: which can be manufac tured. at a low cost.

A further object is to construct: wire braces i n separate units; may be readily secured to the corner members by: welding or brazing;

A further object, isto construct the wire braces with diagonah members. having foot members extending parallel with the corner members and forming with the latter extended: welding surfaces for increasing the: rigidity of the structure.

A further object is to term the braceswith central ribs: forming part of the: diagonal members and secured together in parallel relation: by welding together the parallel portions;

A further object is; tooon-struct wire: braces havingv a minimum number of members; which braces are adaptable forforming light weight studs for vertical walls, or partitions, not sub.- jected to. great strains, and to which braces additional members, anddiagonal. struts may be added for making the braces: adaptable for joists. for floors and ceilings required to carry greater loads.

A further object is; to attach the. foot members. of the braces to the cornermembers. in a. novel manner to facilitate in; welding the parts.

These together with various other novel features of construction and arrangement. of the parts, which will be more fully hereinafter dc.- scribed and claimed. constitute our invention.

Inv the drawings, in which like reference characters refer to li ke parts, I 5 represents the brace shown in Figs. 1 to 3. Said brace is formed of a single wirebentunonitself intodiagonal members: t6, H, M: and t9, extending in a common plane; A'foot member M is formed upon each diagonal member and extends: at right angles to said pl'ane. Transverse connecting members 2i and'ZZ are connected between diametrically op posite pairs of foot members.

Said connecting members 21 and 22 are formed integrally with: the opposite ends of the foot members: relatively to the diagonal members, and said connecting members occupy a different plane firom' the. plane ozfi the diagonal members, thus. forming-means for readily placing the brace in: a transverse: position relatively tothe length of the corner members when the braces and cox nor members: are being assembled.

The upper connecting. member ll-2, as: shown Fig; bent upon itself to form a foot member Z3which: is welded to.- the foot member on the diagonal member Hi.

The members t6 and H form approximately a right angle having a flat portion 25- at the apex, and: the members. I 8 and P9 are also formed in a similar manner with: a flatportion 25. Said flat portions are joined by welding into a central rib: 212, thus forming the brace into a rigid structure. with said paralled. fiat portions 25 and 26 nresenfing' elongated welding surfaces.

Fig.1 illustrates a brace 29 formed of two separate: w-ires each comprising diagonalmembers 30 and 3!, foot members 32 and 33. The foot. members; 33 are each formed with a transverse. connecting member 3E, which latter termimates with atoot member 3 5; The foot members and: 35 are welded together atthe opposite corners of the brace. The diagonal members 341 and 3|: are: connected by a flat portion. 36-. The flat portions: 3610i two similar wires are placed par--- azllel to each other and. form elongated welding surfaces. adapted to be welded into a: central rib 31, forming the brace into a rigid structure.

The transverse braces above described are adapted-I for forming studs 40, shown in Figs. 8 and 9.; for use" in vertical partitions and walls.

studs m are formed of four parallel; longitudinal, corner members 4|, with the braces 5 secured at intervals throughout the length of said corner members; The braces are positioned transversely to the length of the corner members and hold the latter in spaced relation to each other in the form of a rectangular stud.

Each corner member 4| is in the form of an angle bar, and consists of plates 42 and 43 arranged at right angles to each other with the apex of the angle extending outwardly relatively to the center of the stud, as shown in the end View Fig. 8.

The foot members 20 and 23 of a brace, such as shown in Fig. 1, are positioned parallel with the length of the corner members 4| and said foot members are welded to the plates 42, forming welded joints 45. Said foot members provide elongated welding surfaces between the foot members and the plates 42 of the corner bars as shown in Fig. 9, thus increasing the rigidity of the welded joints 45. The foot members extend at right angles to the plane occupied by the diagonal members IE to I9, and also at right angles to the plane occupied by the connecting members 2| and 22, so that each foot member forms a base or foot for rigidly attaching the brace to the corner members, thereby adding rigidity to the diagonal and connecting members and forming a rigid stud comprising a minimum number of parts. 7

The foot members are attached to one angle plate only of each corner member, as shown in Fig. 8. The foot members of the braces are attached to the plates 42 and are located in spaced relation to the plates 43, thereby providing sufficient room for the application of a welding tool between the joints 45 and the apex of the angle of the plates 42 and 43.

The braces 48, shown in Fig. 4, are adaptable for forming floor joists, and the like, where great er rigidity is required than in the studs. The brace 48 embodied in the joist 50, shown in Figs. 10 to 12, is similar to the brace shown in Fig. 1, with the addition of connecting members 52, which are secured to said brace to form a rigid rectangular frame. The connecting members 52 are each provided with foot members 53 and 54, extending at right angles to the length of said members 52, as shown in Fig. 5. Said foot members 53 and 54 are placed parallel with the foot members 20 and are welded to the latter.

A diagonal strut 56 is formed upon the foot member 54 of each connecting member 52, and

said strut terminates in a foot member 51.

The joist 50 includes corner members 4|, similar to those shown in Fig. 8, and between which members are secured the braces 48 by welding the foot members to one of the angle plates 42 of each corner member 4|, as shown in Fig. 11. The struts 56 extend between adjacent braces 48 and also between two parallel corner members 4|, to which the struts are welded as shown in Fig. 10, thus forming the four corner members into a rigid rectangular structure adaptable for use as beams, girders and joists for buildings like structures.

Various changes in the construction and arrangement of the parts may be made, and the novel braces may be applied to different forms of corner members, without departing from our invention.
